Mosquito Definitions

Chapter 1 - Mosquito Control

101. Definitions [formerly paragraph 51]

Unless otherwise specifically provided herein, the following words and terms used in this Part of the sanitary code and all other Parts which are adopted or may be adopted, are defined for the purposes thereof as follows.

  • Community - any incorporated area, or in the case of unincorporated areas, either of the following:
    • A settlement consisting of 25 or more residences per mile of highway frontage
    • A settlement consisting of 25 or more residences within a circle having a 0.5 mile diameter
  • Control Measures - any measures approved by the state health officer which are used in the prevention or control of mosquito-borne diseases. These measures include source reduction, application of pesticides, naturalistic (biological) control, exclusion of mosquitoes, and integrated pest management.
  • Exclusion - exclusion of mosquitoes includes measures of protection against mosquitoes such as screening of openings in dwellings to prevent entry of adult mosquitoes and screening of stored water to prevent egg-laying by mosquitoes and the use of protective clothing and mosquito repellents.
  • Impounded - any body of water formed by the construction or excavation of a basin or the obstruction of surface water run-off in such a manner as to cause the collection of a body of water which could not have formed under natural conditions. Such impounded waters of less than 2 acres of water surface, are not included in this definition, except that in the event an outbreak of disease known or suspected to be transmissible by mosquitoes occurs in the vicinity of such a pond, the state health officer may require that it be subject to the same regulations as larger bodies of impounded water.
  • Integrated Pest Management - integrated pest management as applied to mosquito prevention and control includes a combination of procedures such as exclusion, naturalistic control, source reduction, and the application of pesticides.
  • Naturalistic - naturalistic control involves the use of predators, pathogens (diseases), and other natural antagonists of mosquitoes.

103. General Mosquito Control Regulations [formerly paragraph 52]

Water in man-made containers or man-made basins within 1 mile (1.61 kilometers) of communities shall not be permitted to produce mosquitoes. Tanks and other containers used for storage of water shall have all openings larger than 1/18 of an inch (0.14 centimeters) screened with wire mesh not less than 18 strands to the inch each way (7 strands to the centimeter). Standing water in fountains, basins, and urns in parks, cemeteries, and residential and commercial sites, and water in ponds, pools, borrow pits, ditches, or other depressions or excavations must be maintained free from debris, flotage, and emergent vegetation and stocked with mosquito larvae-eating fish or treated at suitable intervals with federal and state approved larvicide if mosquito production becomes imminent.

[formerly paragraph 53] In the event of an outbreak or imminent outbreak of mosquito-borne disease, the state health officer, may, in addition to the regulations promulgated elsewhere in this Part, require mosquito prevention or abatement measures applied to less usual sources of mosquito production as considered necessary.

[formerly paragraph 54] All persons suspected of having a mosquito-borne infection shall be protected from the bites of mosquitoes unless, and until, the infection is found not to be due to mosquito-borne infection; and if found to be mosquito-borne, protection shall be continued until the infective stage has passed, as determined by the state health officer.

[formerly paragraph 55] It shall be unlawful for any person to create, or cause to be created, conditions favorable for producing mosquitoes by impounding of water unless provision has been made for control measures.

[formerly paragraph 56] In the event of an outbreak or imminent outbreak of mosquito-borne disease, the state health officer may require that any person proposing to impound water, raise the level of existing impounded water, or re-impound water in areas where previous impoundage has been discontinued for one or more seasons, prior to the institution of any construction activities, shall make written application to the state health officer and receive therefrom a written permit for impoundage construction.
